Mechanical intelligent self-adaption two-gear automatic-gear-shifting hub

Abstract

The invention discloses a mechanical intelligent self-adaption two-gear automatic-gear-shifting hub, which comprises a power device, a box body, a transmission shaft and a wheel and further comprises a slow-gear transmission mechanism, a ring body axial outer taper sleeve and a ring body axial inner taper sleeve. The ring body axial outer taper sleeve is sleeved on the transmission shaft and transmitted through a spiral cam pair. The mechanical intelligent self-adaption two-gear automatic-gear-shifting hub has all advantages of an existing cam self-adaption automatic-gear-shifting device, adopts the transmission structure of the spiral cam pair, further decreases radial dimension of an mechanism and thus decreases volume, and greatly prolongs service life. In addition, the spiral structure is stable in transmission and even in stress, and has incomparable stability and smoothness. Therefore, the mechanical intelligent self-adaption two-gear automatic-gear-shifting hub further improves work efficiency, has better energy saving and consumption reduction effects, largely controls vehicle emissions, is more suitable for light vehicles of light bicycles and the like, and greatly improves dynamic property, economical efficiency, driving safety and comfort of vehicles.

Description

Technical field [0001] The invention relates to a motor wheel hub, in particular to a mechanically intelligent self-adapting two-speed automatic transmission hub. Background technique [0002] In the prior art, automobiles, motorcycles, and electric bicycles basically directly control the throttle or current control speed through a speed control handle or an accelerator pedal, or use a manual mechanical automatic transmission mechanism to achieve speed change. The operation of the handle or accelerator pedal completely depends on the operation of the driver, which often causes the operation to be mismatched with the driving conditions, resulting in unstable operation of the motor or engine, and a stall phenomenon. [0003] When the rider does not know the driving resistance, it is inevitable to have the following problems if the rider only operates and controls the speed change device based on experience: 1. When starting, uphill and heavy load, the driving resistance increases, fo...

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a mechanical intelligent self-adaptive two-speed automatic transmission hub, which can not only adapt to the change of driving resistance without cutting off the driving force, but also automatically shift gears and change gears, and solve the problem of motor torque-rotational speed changes. The small size cannot meet the problem of road use under complex conditions. It has good stability, further improves work efficiency, has better energy saving and consumption reduction effects, reduces volume, and further improves service life. It is more suitable for light two-wheeled vehicles and other portable vehicles. vehicle use
